Both are fully deserving Cannes’ Palme d'Or winners. Each film is social commentary on what a broken economic system can force people to do when in dire straits. They both centered on poor urban family, clinging to the fringes of society, who gets by through scheming and stealing.

If you find yourself empathizing with the Kim family in Parasite, it is because the film tried to humanize them by showing their close family bonds and loyalty to one another. You'll see this in Shoplifters too. They are also some twists in the plot of Shoplifters but I shall not spoil it for you. :)
